【Abstract】 A theoretical analysis is presented for the snap-buckling behaviour of dishedshallow shells under uniform loads. By means of the modified iteration method,the second approximate formula of elastic behaviour and set of numerical solutions are given. And effects of parameters and on the snap-buckling behaviour arediscussed.更多还原
